1. A method of depositing a material having a predetermined crystalline phase, comprising the steps of:
- depositing a film over at least a portion of a substrate surface that will enhance the growth of the predetermined crystal phase defined as a first depositing step; and
depositing the material on the film defined as a second depositing step.

Abstract
Hydrophilic and/or rutile and anatase titanium oxide are obtained by sputter depositing titanium metal oxide on a film of zirconium oxide in the cubic phase. Another technique is to deposit a titanium metal on a film of zinc oxide in the cubic phase and heating the coating in an oxidizing atmosphere to provide an anatase and/or rutile phase(s) of titanium oxide.
